"Glory of Kings" is 120fps throughout the process, and the heat control is good.
We have just tested the new generation of Snapdragon 8 mobile platform phones, and we have come to such a common conclusion. Several flagship phones from Xiaomi, Real Me and iQOO are currently performing steadily, and belong to the level that can be bought by looking at the budget and seeing preferences.
Snapdragon 8 from the release, to the actual measurement of the engineering machine, and then to the major brands of mass production machine listing, in fact, with suspense. Many people are very worried about its actual performance and heat, but in the first time after the release of the Snapdragon 8, Aifan participated in the actual measurement of the engineering machine, and there were two places that were impressive at that time: the graphics performance improved a lot, and the heat control was quite good.

The first batch of Snapdragon 8 mass production machines have also been listed, including aifan' many first reviews have focused on performance and heat dissipation, and everyone's conclusions are similar: Snapdragon 8, still quite calm. At the same time, while maintaining "calm", it also continues the performance performance of the engineering machine, and performs well in the peak performance and sustained performance of the game.
However, now that it's 2022, we can actually focus on the other things on the Snapdragon 8 mobile platform, the features that hide in the details but always affect the experience.
A less noticed example is that many of the first cameras in 2021 are from Snapdragon platform phones, such as the first 10-bit HEIF camera phone, the first 4K 120FPS camera phone, the first 1-inch outsole phone, the top DXO phone and so on.
Similar to Snapdragon's baseband, the image part of the Snapdragon mobile platform is not under the spotlight of the front desk, but it is really reassuring as a behind-the-scenes scenes.
On the Snapdragon 8, its image characteristics have been upgraded again, and many shooting functions that were felt out of reach a few years ago have become possible on mobile phones between square inches.
Now many mobile phones have begun 10-bit color depth shooting (generally by the mobile phone ISP to carry out 14-bit data calculation processing), but also with the corresponding 1 billion color screen, compared to the previous 16.7 million colors to take pictures and display, this is a huge progress, no contrast no harm, when in the sunset, or under the scene of the sea and the sky, the delicate natural transition of 1 billion colors is beyond the reach of the latter.
But in theory, the number of colors in nature is infinite, and the 1 billion colors brought by 10bit color depth are not the end of the photo, but one of the key milestones, and the road behind can actually be extended indefinitely. The Snapdragon 8 mobile platform is now equipped with the first smartphone ISP (Image Signal Processor) that supports 18-bit color depth.
Compared with the three 14-bit ISPs of the previous Generation Snapdragon 888, the three 18-bit ISPs of the Snapdragon 8 can process dynamic range data 4096 times that of the former, which means that mobile photography is one step closer to reality.
Dolby Vision is currently the best HDR video format and the most demanding format for shooting and playback equipment, for example, it requires a 12-bit color depth, so supporting 18-bit computation and processing on isps makes dolby Vision shooting well.
Night scene has also been the traditional strength of Android mobile phones, after the mobile phone ISP upgraded to 18bit, the night scene of the Snapdragon 8 mobile phone also has a higher upper limit, this is because we see a bright and clean night view photo, in fact, the mobile phone is synthesized by taking multiple photos of different exposures, some photos are responsible for the purity of the picture, some are responsible for the brightness of the picture, and finally complement each other. Before the Qualcomm Snapdragon low-light engine is generally shooting 6 photos for compositing, thanks to the new 18-bit ISP, this engine has been upgraded to a "super multi-frame engine", which can take 30 photos at a time for compositing, and the night level of the already good Snapdragon mobile phone can be improved again.

As mentioned earlier, mobile photography is often a game of data and calculation. 4K 120fps records twice as much picture as 4K 60fps, and 8K HDR10+ gets more information per frame, marking the transition from being able to shoot 8K video to being able to shoot 8K video well.
At the same time, the Snapdragon 8's 18-bit ISP also supports an interesting feature: a lens can also shoot 64-megapixel photos while shooting 8K video. The reason is also very simple, because the data processing bandwidth of the 18bit ISP is greatly provided, this generation of Spectra ISP can process 3.2 billion pixels per second, the road is wide, the road is good, and it supports multiple heavy trucks to drive side by side.
The advancement of the underlying technology can bring many features, 18bit ISP support "video super resolution" can allow the digital zoom after the picture details to retain more, 18bit RAW image export to professional photographers to provide a broader post-process space.....
Similar image technology updates are still quite a few on Snapdragon 8, such as the increase in face recognition feature points from 100 to more than 300, not only is recognition faster, but the relevant expression capture and emotion judgment are also more accurate. Ultra-wide-angle shots can now reach 140-degree photos without stitching, and algorithms can correct edge distortion.
The support of this generation of Snapdragon 8 mobile platform in imagery can basically be described as "two steps faster than the mainstream", which is of course the self-cultivation of a flagship chip, which is also reflected in more hidden corners.
Sound performance is a mobile phone feature that we accompany all the time, but it is easy to be overlooked, and the support for sound characteristics in the new generation of Snapdragon 8 has also made great progress.
Once upon a time, we mentioned that wireless headphones are connected to mobile phones to listen to music, basically just expect to listen to a ring, do not have much hope for sound quality, high notes do not sting, bass is not boring, thank God.
However, the field of smartphone manufacturers has been involved in smart watches and wireless headphones, and it is not difficult to find a wireless headset with low latency, long endurance, good noise reduction and good sound quality. Based on the Snapdragon 8 mobile platform and the Qualcomm FastConnect 6900 mobile connectivity system, the Snapdragon listening technology released last year has also been enhanced.
The two most notable features are "CD-level lossless wireless music" and "ultra-low latency voice synchronous backhaul", the former is quite easy to understand, that is, the sound quality is further improved, approaching the wired level. The latter makes the game voice communication experience close to or beyond the limits of human perception, making the multiplayer team game experience more immersive.
The game is a synthesis of audio and video, and it is also a part that considers the comprehensive strength of the mobile platform. As mentioned at the beginning, the graphics performance of this generation of Snapdragon 8 has improved greatly, which has laid a solid foundation for its game performance.
In this traditional strength of Qualcomm Snapdragon, the game features are worth talking about more than frame rate running scores.
For example, variable resolution rendering (VRS), a technique that can be compared to a variable refresh rate in display technology. In a picture, in fact, many places do not need so high resolution, such as the blank space in the background of the picture, blue sky, etc., the resolution is lower, it does not matter, and the road surface and grass in the picture do not need the main body to be so fine, the center of gravity of the picture and the visual part can retain the highest resolution, so for different parts of the picture to adjust the resolution, do fine management, can reduce the load of the GPU, in the same picture quality, improve the frame rate, reduce power consumption. VRS was first supported on the Snapdragon 888, and now the Snapdragon 8 platform can support the more powerful VRS Pro, the Variable Resolution Rendering Premium, which provides game developers with finer granular control when tuning game performance.
Not only do players pay attention to prejudgment in the game game, but the chip also has to prejudge the game screen. Another game feature that increases frame rate and reduces power consumption is the Adreno Graphic Motion Engine, which leverages historical frame data and GPU optimization of motion estimation, enabling games that support this feature to generate more frames, allowing games to run at double frame rate while maintaining nearly the same power consumption.
Realism and immersion have always been the goal of game development, so over the years, technologies such as spatial audio, stereoscopic rendering, and ambient light have also been born, all in order to "fake the truth". Snapdragon 8 supports these features, can make the gunfire, footsteps, explosions in the shooting gunplay game are clear and have a sense of orientation, so that the smoke of grenade explosions or the clouds in the mountains flutter more in line with the laws of physics, so that the effect of direct refraction reflection of light is close to the real world.....
Leitz Looks mode
It can be seen that when talking about images, it is inseparable from AI, when talking about sound, the game is an important scene, and then talking about the game, the sound is an inseparable part. So in many classified scenarios, the technology is cross-cutting, and AI is universal. The SNAPDR 8's AI capabilities are almost ubiquitous, with the explicit leitz Looks mode built in, allowing the phone to take Leica-style Photos; AI can also track the user's health status through sound, such as mental health, or whether the user has asthma. There are more hidden outputs of AI, and even bad signals can be optimized by AI: for example, Snapdragon 8 can intelligently detect the user's holding posture, thereby adjusting antenna performance to optimize the signal.
Today, when the Snapdragon 8 mobile phone has begun to be listed in a large area, looking back at its new features is actually a process of learning the new from the past, and if the timeline is extended further, you can feel the process of technological development even more. One technical detail that impressed me: many games have audio parts running entirely on the CPU, but many of the game's masterpieces have a lot of audio objects, even up to 128, and if they are all running on the CPU, the load and power consumption are not small; so Qualcomm, together with partners, transferred these additional CPU tasks to Hexagon processors to achieve better results and greater energy efficiency.
Variable resolution rendering, image motion engines and other new features are all like this, a technology from scratch, from rough to fine, not only the process of technology, but also the experience of the leap.
